RepositorySourceException thrown when creating file using WebDav client and FileSystem connector

When creating new file in Modeshape repository (configured to use Filesystem connector) using a WebDav client, there is a RepositorySourceException thrown. I tried WebDav methods provided in Jackrabbit Webdav package and also WebDav methods from Sardine framework, both resulted in org.modeshape.graph.connector.RepositorySourceException: Attempt to set or update invalid property names: [jcr:encoding]

Here is a code snippet which uses PutMethod class from Jackrabbits's WebDav package:

try

{ DavMethodBase put = new PutMethod("http://127.0.0.1:8080/modeshape-webdav/file6.txt"); initClient().executeMethod(put); System.out .println(put.getStatusCode() + " " + put.getStatusText()); }

catch (Exception e)

{ System.out.println(e.getCause()); e.printStackTrace(); }

and here's a stacktrace SOA-P's console:
